Hyperprolactinemia, characterized by abnormally high levels of prolactin, may cause galactorrhea (production and spontaneous flow of breast milk), infertility, and menstrual disruptions in women. In men, it can lead to hypogonadism, infertility and erectile dysfunction. Prolactin is crucial for milk production during pregnancy and lactation.
Direct treatment is geared toward resolving hyperprolactinemic symptoms or reducing tumor size. Patients on medications that cause hyperprolactinaemia should have them withdrawn if possible. Patients with hypothyroidism should be given thyroid hormone replacement therapy. When symptoms are present, medical therapy is the treatment of choice ...
Galactorrhea can also be caused by antipsychotics that cause hyperprolactinemia by blocking dopamine receptors responsible for control of prolactin release. Of these, risperidone is the most notorious for causing this complication. [5] Case reports suggest proton-pump inhibitors have been shown to cause galactorrhea.
The "atypical" antidepressants mirtazapine and bupropion do not increase prolactin levels (bupropion may actually decrease prolactin levels), and hence there may be no risk with these agents. [22] Other drugs that have been associated with mammoplasia include D-penicillamine, bucillamine, neothetazone, ciclosporin, indinavir, marijuana, and ...
[13] [2] [10] [14] Secondary to increased prolactin levels, breast changes, milk outflow, menstrual irregularities, and hypogonadism can occur. [2] [10] [14] Domperidone may also cause QT prolongation and has rarely been associated with serious cardiac complications such as sudden cardiac death.
Prolactin inhibitors are mainly used to treat hyperprolactinemia (high prolactin levels). [1] Agonists of the dopamine D 2 receptor such as bromocriptine and cabergoline are able to strongly suppress pituitary prolactin secretion and thereby decrease circulating prolactin levels, and so are most commonly used as prolactin inhibitors.

Gestational diabetes is a form of diabetes that is first diagnosed during pregnancy and can accordingly cause high blood sugar that affects the woman and the baby. [9] In 10 - 20% of women whose diet and exercise are not adequate enough to control blood sugar, insulin injections may be required to lower blood sugar levels. [9]
This leads to misdiagnosis of hyperprolactinaemia in many people, especially those with other symptoms, such as infertility [4] or menstrual problems. [5] "Macroprolactin" is most commonly a complex of prolactin and IgG (typically IgG4), displaying a molecular weight of approximately 150 kDa (which is hence 6–7 fold higher that the native ...
